Definitions

  • the invention relates to a pasty floor filler and a kit-of-parts for producing a ready-to-use floor filler.
  • the invention also relates to the use of such a kit-of-parts for producing a ready-to-use floor filler.
  • the invention relates to a method for producing a ready-to-use floor filler.
  • Floor fillers are known in different compositions.
  • such floor fillers consist of hydraulic and / or non-hydraulic binders, mineral aggregates and so-called additives, such as wetting agents, defoamers, liquefiers, retarders or accelerators.
  • floor fillers In contrast to wall and ceiling fillers, which are also offered as ready-to-use fillers, floor fillers have to meet special requirements, especially with regard to their hardness, because of the higher mechanical impact and shock loads.
  • powdered dry floor leveling compounds based on cement or calcium sulfate are predominant. They must be mixed with water immediately before use on the construction site in order to obtain a ready-to-use floor filler.
  • floor fillers have been used more and more directly as a floor covering and not just as a substrate for another floor covering such as PVC, carpeting, laminate or parquet. Since the floor filler often forms the topmost and thus visible floor covering today, increased requirements are placed on the surface character and decorative optical properties such as structure and color of the floor filler.
  • color concentrate and / or decorative lumpy additives such as sand, metal chips, fibers or the like are added to the floor filler during the mixing process.
  • the products and processes used today also have the disadvantage that for every sack of powdery filler that has to be mixed with water to make a ready-to-use floor filler, the decorative additives such as color concentrate or metal chips have to be weighed again and mixed in. In many cases, this means that there are color differences between the separately mixed batches of floor fillers. Furthermore, when adding creative additives such as metal chips, differences can occur between the individual batches arise in the concentration and distribution of the lumpy additives.
  • Another disadvantage is the time it takes to weigh and mix the creative additives such as color concentrate or metal chips, as well as the need to provide a precision balance on the construction site.
  • a coating composition in the form of a 2-component kit which contains a first and a second component, the first component containing plaster of paris and / or cement which is dispersed in a water-miscible organic solvent, and the second component a water-soluble one Polymer, and wherein the first and second components are miscible with one another, thereby forming a cured coating composition.
  • the object of the present invention was now to provide a kit-of-parts for producing a ready-to-use floor filler, a use of this kit-of-parts, a pasty floor filler and a method for producing a ready-to-use floor filler provide which largely avoid or at least reduce the aforementioned disadvantages and problems of the prior art.
  • kit of parts according to the invention for producing a ready-to-use floor filler comprises the pasty floor filler according to the invention and a hardness component.
  • kit-of-parts we mean a multi-component system, a set of parts and / or a set or a group of components or individual parts.
  • a kit-of-parts is provided, the components of which only have to be mixed with one another to produce a ready-to-use floor filler.
  • the paste-like floor filler according to the invention is the paste-like floor filler according to the invention.
  • pasty is to be understood as meaning in particular easily flowable.
  • Other floor leveling compounds which are known from the prior art, begin to harden on contact with water during the production of a pasty floor leveling compound. Therefore, the previously known floor leveling compounds must be stored as a dry mixture and may only be mixed with water shortly before use.
  • the paste-like floor filler according to the invention which is contained in the kit-of-parts according to the invention, has the advantage that it can be stored in paste form without hardening.
  • hardening of the floor filler obtainable by the kit-of-parts according to the invention takes place only through the hardness component, which is contained as a further component in the kit-of-parts according to the invention.
  • hardness component is understood to mean any substance or any mixture of substances which, when mixed with the inventive pasty floor leveling compound also contained in the kit of parts according to the invention, leads to the hardening of the floor leveling compound thus obtainable.
  • the kit of parts according to the invention is used to produce a ready-to-use floor filler.
  • the kit of parts according to the invention is particularly suitable for producing a floor filler based on a hydraulic binder.
  • binding agents When binding agents are mentioned here, all substances are meant through which solids have a fine degree of division, for example powder, with one another or on can be glued to a base.
  • hydraulic binders to be binders which cure both in air and under water.
  • Examples of hydraulic binders are: cement, mixed binders, hydraulic lime (trass), cement-based plaster and wall binders.
  • Optimal results can be achieved with the kit-of-parts according to the invention for producing a cement-based floor filler.
  • Cement has the advantage that the floor filler obtained according to the invention has a particularly high degree of hardness. This makes it particularly suitable as a floor filler, as floor fillers, in contrast to wall fillers, are exposed to higher mechanical impact and shock loads.
  • kits-of-parts according to the invention are such that the floor filler obtainable from the kit-of-parts is self-leveling before it hardens.
  • Self-leveling floor filler in the context of this invention also includes so-called flowing screeds, mortars, leveling or leveling compounds.
  • Such self-leveling floor fillers have the advantage that they are flowable and pumpable and thus time can be saved when applying the floor filler.
  • self-leveling floor fillers automatically adjust the height and thus lead to particularly flat surfaces after hardening. This allows them to be used for leveling (leveling) uneven surfaces or has the advantage that the surface is in front Application of the floor filler does not have to be straightened beforehand.
  • a particular advantage of the floor filler obtainable with the kit of parts according to the invention is that it can be used as a top coat, i.e. it can form the top floor covering in living and outdoor areas.
  • kits-of-parts can be produced with the kit-of-parts.
  • the kit-of-parts according to the invention can be used to produce floor fillers which, after hardening, have a high mechanical strength.

  • the floor coverings that can be produced with the kit of parts according to the invention are characterized by adhesive tensile strength values according to prEN 13892-8 of at least> 1.0 N / mm 2, preferably at least 1.5 N / mm 2 . Practical tests have shown that the kit-of-parts according to the invention can be used to produce floor coverings which, according to DIN EN 13813, are to be classified in the wear resistance class against rolling stress RWA10.
  • both the inventive pasty floor filler and the hardness component have a light reference value Y of at least 50, particularly preferably from 65 to 90 , exhibit.
  • the cementitious floor fillers usually used have a mostly dark inherent color with a lightness value Y of 30 and less due to the high iron oxide content in the hydraulic binders.
  • the floor fillers obtainable according to the invention with a light reference value Y of at least 50 can also be used as a light surface coating over a large area and can be colored as desired using colorants.
  • the paste-like floor filler according to the invention, the hardness component and / or the floor filler that can be produced using the kit-of-parts according to the invention should have a lightness value Y of at least 50, preferably between 65 and 90.

  • CIE Commision International de l'Eclairage
  • a lightness value Y of 0 means black; and a lightness value Y of 100, white.
  • the inventive pasty floor leveling compound contained in the inventive kit of parts can already be colored.
  • a sufficient amount of colorant selected from the group consisting of organic and / or inorganic pigments and / or pigment preparations is added in relation to the desired coloration.
  • Cement-compatible colorants or pigments or pigment preparations are used for the production of a cement-based floor filler.
  • colorants or pigments are considered cement-safe if they are resistant to bases.
  • cement-safe colorants or pigments are: iron oxide black, manganese black, iron oxide red, iron oxide yellow, iron oxide brown, umber, ocher, Terra die Siena, Naples yellow, chrome oxide green, chrome oxide hydrate green, titanium white R, anatase, ultramarine blue and manganese blue.
